Answer:

The answer to your question is z = -3

7z = -21

Clear z z = $\frac{-21}{7}$

z = -3

Select the two binomials that are factors of this trinomial.

const2013 [10]

$\huge{ \mathfrak{ \underline{question : }}}$

Select the two binomials that are factors of this trinomial.

$x_2 + 8x + 12$

$\huge{ \mathfrak{ \underline{Answer : }}}$

${x}^{2} + 8x + 12$

${x }^{2} + 6x + 2x + 12$

$x (x + 6) + 2(x + 6)$

$(x + 2)(x + 6)$

We got the factors as :

$A. \: (x + 6)$

and

$D. \: (x + 2)$
